Basie Physies PHY 114-W-0 Departawnt of Physical and Computer Scies Medgar Evers College Quiz 7 Directions Write out your legible answers in the space provied I. If a particle is mowing in a uniform eirele with a radius od 5 w and a wlocity of 300 m/min, what is ins period 2. If the total accelerstion of a object is 60m2 and its radial neederation is 30 m/2 due south what is tangential acceleration of the objeet and the direction of the object? 3. A car moving with a constant acceleration thst started froen rest Over a bump, which has a raius of 100 m6 seconds in its ride What is the magnitode of the total acceleration of the car? If the same force is applied on two objects of mawes 10 kg and 18 kg and the acceleration of the objet of the smaller mass S4 m/s*. vhat is the acorkratku of the larger object? Extra Credit: Two objects are attached to the ends of a string and placed over a pulley I the mas of the objects are 16 kg and 30 kg, what is the accelerat on of the system and the teicn of the string

Answer 1

Solution 1)

Distance travelled= 2*3.14*5= 31.4 m

Given, velocity=300 cm/min = 0.05 m/sec

Now, time period= 31.4/0.05 = 628 sec (Ans)
